1 Freescale i.MX audio complex with S/PDIF transceiver
3 Required properties:
5   - compatible          : "fsl,imx-audio-spdif"
7   - model               : The user-visible name of this sound complex
9   - spdif-controller    : The phandle of the i.MX S/PDIF controller
12 Optional properties:
14   - spdif-out           : This is a boolean property. If present, the
15                           transmitting function of S/PDIF will be enabled,
16                           indicating there's a physical S/PDIF out connector
17                           or jack on the board or it's connecting to some
18                           other IP block, such as an HDMI encoder or
19                           display-controller.
21   - spdif-in            : This is a boolean property. If present, the receiving
22                           function of S/PDIF will be enabled, indicating there
23                           is a physical S/PDIF in connector/jack on the board.
25 * Note: At least one of these two properties should be set in the DT binding.
28 Example:
30 sound-spdif {
31         compatible = "fsl,imx-audio-spdif";

33         spdif-controller = <&spdif>;
34         spdif-out;
35         spdif-in;
